Lamination Press

The GD series high speed precision press:Our company GD series high speed precision automatic line is mainly applied in theindustry of manufacture the motor rotor and stator, electron, electric appliancedome and connector.The main specification & features1 Our products adopt four-column & double points structure, with one promoted cylinderon each of the four columns. The sliding block can be promoted in a largerange on the guide pillar by the function of the cylinders. Thus it is convenientto change sub-dies and make some tooling maintenance. And the cylinders also havethe function of hydraulic overload protection.2 We change the traditional crankshaft connecting rod structure to crankshaft slidingblock structure of the spindle power structure of the double points, thus it notonly increase the rigidity but lay the double power point with a farther distance,which increase the capacity to bear eccentric load in the direction. At the otherdirection of the slide, namely the direction of the forward and backward guideway, we change the single group roller guide rail guidance to up and down doublegroups roller guide rail guidance. Because of the long distance of the up anddown roller, the guide guidance is with high precision and the capacity of thebearing the eccentric load of the whole press of is very strong.3 Main parts such as pedestal, upper beam and sliding block of the press are allprecision casting formed to fluid state sand. Because of good nature of anti-vibrationand anti-distortion after aging treatment, it can keep long-time precision,diminish the noise and make the press with a good shape.4 Installed eccentric covers at both sides of the spindle, assembled the counterweightclump inside the eccentric covers to eliminate the imbalance aroused by theeccentric covers.5 Some balancing springs are installed on the upper beam of the press to balancethe weight of the slide parts and the upper mold, and promote precision throughthe balance adjusting bolt.6 The whole production line adopts PLC control. The variable parameter can be inputby the human-machine.7 Because of adoption of the oil mist lubricative technology, it can greatly reducethe hot- deformation and promote the precision of the bottom stop.Press GD63 series specifications: Capacity: 630kNLimit of capacity: 3mmStroke length: 30mmStrokes per minute: 150 400spmDie height: 350mmSlide adjustment: 50mmSlide area: LR762 x FB530mmBolster area: LR950 x FB600mmBolster opening: 700 x 120mmMain motor: 11kW x 4P Press GD125 series specifications: Capacity: 1,250kNLimit of capacity: 3mmStroke length: 30mmStrokes per minute: 150 320spmDie height: 400mmSlide adjustment: 50mmSlide area: LR1,200 x FB600mmBolster area: LR1,200 x FB650mmBolster opening: 1,000 x 200mmMain motor: 15kW x 6P Press GD200 series specifications: Capacity: 2,000kNLimit of capacity: mmStroke length: 30mmStrokes per minute: 160 310spmDie height: 420mmSlide adjustment: 50mmSlide area: LR1,470 x FB700mmBolster area: LR1,700 x FB950mmBolster opening: 1,270 x 250mmMain motor: 30kW x 6PPacking: wooden box
